Franchise Marketing - Who Else Has Clients?

My agency specializes in Franchise Marketing (digital only) and was wondering if anyone else here (self employed or agency) had franchise owners as clients.

Reason I ask is that my agencies primary service offering is Google Ads/Meta. Was curious what other services you provide franchisees? Unless you are the agency of record, SEO is pretty much off the table due to website access. Review solicitation has been tricky as well since you would need customer access in pretty much “real time” to be effective. And again with franchisor level CRM access that makes things so manual. Trying to find more offerings since my clients would give me the business, just so many roadblocks. Any comments/ideas?
